* Update version v1.6.0 -> v2.1.0
* expose container runtime socket to kube-router
* kube-router loadbalancer controller
* Add access / information that is needed by the load balancer
controller in kube-router.
* add access to endpoint slices for services controller
* enable hairpin mode on kube-router
* There are integration tests in kops that expect that hairpin
functionality is always enabled, as such we now enable hairpin-mode
in kube-router by default.
* enable hostPID access
* kube-router now requires access to the host's process namespace. See
https://github.com/cloudnativelabs/kube-router/pull/1584 for more
information.
Add cluster.Spec.Containerd.SELinuxEnabled field that enables SELinux in
containerd.
With SELinux enabled, all pods that use HostPath volumes must run with
SELinux label `spc_t`, otherwise SELinux denies the pods to touch the host
filesystem.
